Clipper and Traffic Analysis

Does anyone here have any thoughts as to whether Clipper enables traffic analysis or tracing more easy than it normally is under Switching System 7?

SS7 uses out-of-band signalling. The clipper LEAF is an in-band signal. Therefore a tap for clipper yields two kinds of information, content and identities. Tapping an SS7 signalling network is more expensive and more difficult to justify. More expensive because it runs packet-switched, more difficult because it's not the conversation of any particular party except the phone company. Eric
